Some To Do's Don't Show

I click on Starred view and only 9 of my 10 starred tasks show. And there is a not at the bottom of the page saying that 1 is not showing due to filters; it has a link that says "Turn Filters Off". Clicking that does absolutely nothing.

Plus, I have not set a filter. How and why does this occur? I am trying to view by Starred and sort by Folders withing that. So I have the "Starred" view selected, and in "Sort" I have "Folders" selected.

1 - Why does this message show? (I do NOT have a separate filter set)

2 - What is the "Turn Filters Off" supposed to do?

3 - Do filters ever get set silently without a user actively setting it up? Or is "Sort" somehow synonymous with "Filter" in Toodledo?

You found a bug. Thanks for pointing this out. The missing starred tasks are actually tasks that you have completed already, but due to the bug they are sill being counted as active. This will be fixed shortly.
